210.8(B). Your facility is not a dwelling unit. Your receptacles are not 125 volt rated. Therefore, they are not required to have GFCI. It is up to the owner, as perhaps represented by the engineer or the contractor, to decide whether it is a good idea to do it anyway.

I wonder if this hood has a fire-suppression system, and whether shut-down of power under the hood is required.

It does not have fire suppression.
